What did you do?

const value = defineModel({
  get: (value: number | string) => {
    if (typeof value === 'number' || (typeof value === 'string' && value && !isNaN(Number(value)))) {
      return new Decimal(value).div(finalUnit.value).toNumber()
    }
    return undefined
  },
  set: (value: number) => {
    if (typeof value === 'number') {
      return new Decimal(value).mul(finalUnit.value).toNumber()
    }
    return undefined
  }
})

What did you expect to happen?
I expect eslint to pass all checks, including no warnings.

What actually happened?

But it threw a warning on defineModel：warning Prop "modelValue" should define at least its type vue/require-prop-types

For adding type information to defineModal, you can refer to the Vue documentation.
